Abstract: Aspects are provided which improve RLM by allowing a UE to apply a longer monitoring window for out-of-sync determinations before the UE triggers an RLM timer for in-sync determinations. The UE first obtains a reference signal from a base station. The UE then determines multiple groups of consecutive out-of-sync indications in response to the reference signal. For example, the UE may perform looped out-of-sync monitoring, multi-cell or carrier monitoring, or a combination of such monitoring to determine the multiple groups of out-of-sync indications. Afterwards, the UE triggers the RLM timer in response to determining the multiple groups of consecutive out-of-sync indications. As a result, the UE may perform additional out-of-sync monitoring during RLM before proceeding with in-sync monitoring, thus allowing the UE to account for rapid BLER changes (ping-pong effects) that may occur in HAPS systems due to tropospheric turbulence and enabling more accurate RLM determinations and minimal RLF detections.
